Annotation: | lasers as surgery = LASER SURGERY + disease /surg, not /radiother; low-intensity lasers = LASER THERAPY, LOW-LEVEL; laser injuries = LASERS /adv eff + organ /inj but do not coordinate with RADIATION INJURIES or any BURNS term; effect of laser as radiation: coordinate IM with anatomical term, organism or chemical substance /rad eff (IM); do not index under source of light (ARGON; XENON; etc.) unless the point of the article & then probably NIM without qualif; laser surgery of cataract = LASER SURGERY (IM) + CATARACT EXTRACTION (IM)

Scope note: | An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the visible, infrared, or ultraviolet regions of the spectrum. They are capable of producing immense heat and power when focused at close range and are used in surgical procedures, in diagnosis, and in physiologic studies. Lasers used at low power, transmitting light not heat, have been used in wound healing and pain control (LASER THERAPY, LOW-LEVEL).
